Molecular characteristics of SP cells. The protein expression of E-cadherin, Vimentin, Twist, Stat3, p-Stat3 and nuclear NF-κB was detected by Western blot analysis (A). IL-6 mRNA and protein level were measured by real-time reverse transcriptase PCR and ELISA respectively (B and C). *p < 0.05 vs. non-SP cells group.
